STOVE-BOARD.

SPECIFICATION forming part of Letters Patent No. 273,582, dated March 6, 18.88.

l Application tiled January 22, 1883. (No model.) i

To all whom it may concern Be itknown that I, HENRY C. MILLIGAN,a citizen ofthe United States, residing at South Orange, county of Essex, and State of New Jersey, haveiiivented new and useful Improvements in StoveBoards, ofwhich the following is a specification.

My invention relates to certain new and useful improvements inl what are known in the trade as stove-boards.

It has for its object the construction of a cheap, durable, and highly ornamental structure, which shall atthe same time be substantially fire-proof; and with these ends in view my invention consists of a stoveboard composed of artificial stone or cement of any de! sign or color, formed within and supported and confined by a surrounding rim or frame kof metal or wood, and with or without a bot# tom, substantially as hereinafter fully eX- plaiiied. t

My invention also consists in details of construction, hereinafter described, for insuring the retention of the stoneor cement within the frame.

In the accompanying drawings, Figure 1 represents a plan view of one of my improved stove-boards; Fig. 2, a cross-section of the same; Fig. 3, a similar view, showing another means for holding the cement in place; Fig. 4, a similar view, showing a modification of the surrounding and confining frame, and illustrating au intermediate binder composed of wire-gauze; and Fig. 5, a cross-section showing an iron grating arranged within the ceinen't in lieu of the pins, dovetails, or gauze shown in the other figures. I have illustrated the several means shown in the Adrawings to indicate that a large variety of means may be employed to strengthen and support or concrete the artificial sto'ne or cement without departing from the spirit of my invention.

Similar letters indicate like partsin the several figures.

`A represents a body composed of artificial stone or cement, which I cast within' a binding and supporting frame, B, the upper edge or sides ot' which are turned inwardly, as clearly shown in the sectional views, to prevent vertical movement or displacement of the body, in an obvious manner, and, in addition to the inwardly turned edges of the frame, I provide dovetail strips C, as seen at Fig. 2, or headed or roughened pins, as seen -at Fig. 3, or wire-gauze, asillustrated at Fig.

4, or a grating, as seen at D, Fig. 5. The frameB may be formed with a bottom, asshown at Figs. 2 and 3, or with a narrow flange, as seen at E, Fig. 4..

At Fig. 4, I have showna peculiar construe 6o tion of traine which I have found particularly advantageous, and which` consists in turning the upper edge downwardly in an oblique line below the plane occupied by the top surface ofthe body A, so as to form a double key to hold -the body in place.

Of course,.in the formation of my improved stove-board any desired color may be given to the body, and any special design may he adopted, and it will also be understood that .7o the general contour of the surrounding frame may be varied to suit the fancy of the market.

lI am aware that stove-boards per se are not new, and I- am also aware that artificial stone made in any desiied shape and color is not new, and that stove-boards lhave lbeen made composed of a metallic frame provided with dead-air chambers, and an upper receptacle filled or finished ofi" with asbestus, cork, plaster, or other non-conducting material, and 8o that metallic shells spun or otherwise formed have been iilleil from the under side with nonconducting material; but I ani not aware that it has ever been suggested prior to 'my invention to form anornainental noncon 85 i ducting board of artificial stone or cement having a surrounding and supporting metallic or other rim or frame projecting over and confining. at the edges 'the contained stone or cement in place. This iiovelt'eature of con- 9o struction is essentially important and necessary in such heavy boards, for the reason that the stone or cement is very liable to becomeA displaced in transportation and handling.

What I claim as new, and desire to secure by Letters Patent, is

1. As anew article of manufacture, astoveboard composed of artificial stone or cement confined and surrounded at its upper edges by an inwardly-projecting ornamental snproo porting rim or frame, substantially as shown and described.

2.'The surrounding and confining frame B, having its upper inwardly-projecting edge 5 turned obliqueiy downward below the upper horizontal plane. substantially as and for the purposes set forth.

In testimony whereof I have. hereunto set my hand. in the presence of two subscribing witnesses.
